White iPhone 4 starts to get Best Buy, The Source shelf space

This shelf tag was apparently spotted this weekend at a Best Buy in Houston, and it speaks for itself: white iPhone 4, AT&T, $599.99 off contract (the same price as the black). Of course, we all know this thing is coming within the next few weeks at this point -- there's just too much evidence pointing in that direction -- but the fact that we've got big box retailers printing and placing tags for it now suggests that it's coming sooner rather than later. Oh, and in case you're wondering, that QR code link is dead at the moment -- we've linked it below in case you want to give it a shot.
